There are several common ways that new mineral crystals form and grow. Perhaps the simplest is when minerals form through the cooling of molten rock and the atoms bond together into mineral crystals.
In an untamed and lonely part of Wyoming’s high desert sits a deposit of gold so large, and so vast, that even today its volume remains a mystery. With an aerial extent of over 10 square miles and a depth of nearly 7,000 feet...
This was a tough task and it required really fast speed and perfect gold recovery, with 210 gold panners competing to advance.
A few years ago I had a tremendous opportunity to visit Australia and hunt for gold there. The geology of the gold deposits there was somewhat different from what I was used to here in the US. I learned a lot about greenstone belt gold deposits while prospecting them in person, and it was an amazing trip.
Greenstone is a hard, tough, altered igneous rock, usually dark green in color. The term “greenstone” has been loosely applied to all greenish rock, including peridotite, dunite, jade, serpentine, and even hydro thermally altered rocks in mining districts. True greenstone is...
